## Description

On January 11, 2017, the NRC issued a Notice of Violation to Rozell Testing Laboratories, LLC, for a Severity Level III violation. The violation involved the failure to use a minimum of two independent physical controls that form tangible barriers to secure portable gauges from unauthorized removal when the portable gauges were not under the control and constant surveillance of the licensee as required by 10 CFR 30.34(i). Specifically, as of May 19, 2016, the licensee only used one independent physical control, a locked cabinet, to secure the portable gauge from unauthorized removal during business hours when the gauge was not under the control and constant surveillance of the licensee.
